Cats are known for their independent and solitary nature, but some felines can coexist peacefully with other cats. However, there are times when cats don’t get along with each other, and cat owners need to recognize the signs of feline aggression and tension.

One way to tell if cats don’t like each other is through their body language. For example, cats feeling threatened or aggressive may puff up their fur, flatten their ears against their head, and hiss or growl at the other cat. They may also swat at each other or engage in physical fights.

Another sign that cats don’t like each other is their behavior. Cats not getting along may avoid each other, hide, or mark their territory with urine or feces.

They may also become more vocal, meowing or yowling more often than usual. Understanding these signs can help cat owners intervene and prevent their cats from getting into serious fights or injuring each other.


Aggression and Conflict


Cats are known for their independent nature, but sometimes they just don’t get along with each other. As a result, aggression and conflict can arise between cats for various reasons, including territorial disputes, fear, or simply not liking each other.

It’s important for cat owners to be able to recognize the signs of aggression and conflict between their cats to prevent serious harm.


Physical Altercations


Physical altercations between cats can be dangerous and result in serious injuries. Signs of physical aggression include hissing, growling, swatting, biting, and scratching. Cats may also puff up their fur and arch their backs to appear larger and more intimidating.

If two cats are engaged in a physical altercation, it’s important to intervene immediately to prevent serious harm. Owners should never try to physically separate fighting cats with their hands, as they may be bitten or scratched. Instead, they should try to distract the cats with a loud noise or by spraying them with water.


Verbal Altercations


Verbal altercations between cats are less dangerous than physical altercations but can still be a sign of underlying conflict. Cats may hiss, growl, or yowl at each other to establish dominance or express their displeasure.

Owners should pay attention to the context of the verbal altercation to determine if it’s a sign of more serious conflict. For example, if one cat hisses at another cat when they’re both eating from the same bowl, it may be a sign of food aggression. In this case, owners should provide separate food bowls to prevent future altercations.

In conclusion, aggression and conflict between cats can be severe for owners. However, by recognizing the signs of physical and verbal altercations, owners can take steps to prevent serious harm between their cats.


Body Language


Cats communicate with each other through body language. Understanding their signals can help determine whether cats like each other or not. The following sub-sections explain how different body language cues can indicate that cats don’t like each other.


Tail Position


A cat’s tail position can reveal its mood. When a cat is happy, it holds its tail upright. However, when a cat is feeling threatened or aggressive, it will puff up its tail and hold it low to the ground. If a cat’s tail is twitching or lashing back and forth, it is a sign of agitation.


Ears and Whiskers


A cat’s ears and whiskers can also provide insight into their mood. When a cat’s ears are forward, it is alert and interested. However, when a cat’s ears are flat against its head, it is a sign of fear or aggression. Similarly, when a cat’s whiskers are pulled back, it is feeling threatened or uncomfortable.




A cat’s posture can indicate whether it is feeling confident or fearful. When a cat is feeling confident, it will stand tall with its head held high.

However, when a cat feels threatened, it will crouch low to the ground with its ears flattened against its head. Additionally, if a cat arches its back and hisses, it is a sign of aggression.

Overall, understanding a cat’s body language can help determine whether they like each other or not. By paying attention to their tail position, ears and whiskers, and posture, it is possible to identify signs of discomfort or aggression.


Territorial Behavior


Cats are territorial animals, and this behavior can sometimes lead to conflicts with other cats. When cats feel threatened or uncomfortable in their territory, they may display various signs indicating their displeasure.




One way cats show territorial behavior is by marking their territory. This can be done by spraying urine or leaving scent marks with their paws or cheeks. If a cat is marking in an area where another cat has already marked, it can lead to a territorial dispute.


Hiding or Avoiding


Another sign that cats don’t like each other is when they hide or avoid each other. If a cat is constantly hiding or avoiding another cat, it may be a sign that they are not getting along. This behavior can also be a sign that one cat is dominating the other, and the submissive cat is trying to avoid conflict.


Aggressive Behavior


Territorial behavior can also manifest in aggressive behavior. This can include hissing, growling, swatting, or even fighting. If cats engage in aggressive behavior towards each other, it may be a sign that they are not getting along.

In summary, territorial behavior is a common cause of conflict between cats. Signs of territorial behavior include marking, hiding or avoiding, and aggressive behavior. Therefore, monitoring cats’ behavior and intervening if necessary to prevent conflicts from escalating is essential.


Environmental Factors


When it comes to cats not liking each other, the environment they are in can play a significant role. Here are two environmental factors that can contribute to cats not getting along:

Resource Competition


Cats can be very territorial animals, and they may become aggressive towards each other if they feel like their resources are being threatened. This includes food, water, litter boxes, and even toys.

If there aren’t enough resources to go around, cats may start to fight over them, which can lead to a breakdown in their relationship.

One way to address resource competition is to make sure that each cat has their own food and water bowl, litter box, and toys.

It’s also a good idea to have multiple litter boxes and water bowls available, especially if you have more than two cats. This can help prevent cats from feeling like they need to compete for these resources.


Lack of Space


Cats are also very territorial about their physical space. If they feel like they don’t have enough room to themselves, they may become stressed and start to act out towards other cats.

This can be especially true in multi-cat households where there isn’t enough space for each cat to have their own designated area.

One way to address this issue is to make sure that each cat has their own space to retreat to when they need some alone time. This can be a separate room or even just a designated area in a larger room.

You can also provide plenty of vertical space, like cat trees or shelves, to give cats more room to explore and play without getting in each other’s way.

By addressing these environmental factors, you can help create a more peaceful and harmonious environment for your cats to live in.




In conclusion, it is essential to pay attention to cats’ body language and behavior when introducing them to each other. While some cats may take to each other immediately, others may require more time to adjust. Signs that cats do not like each other include growling, hissing, swatting, and avoiding each other.

It is important to note that not all cats will get along, and it is essential to respect their boundaries and personalities. Therefore, if introducing cats, it is recommended to do so slowly and gradually, providing separate areas for each cat to retreat to if needed.

Additionally, providing resources, such as food, water, and litter boxes, is essential to avoid cois necessary competition and conflict. Finally, if cats continue showing signs of aggression towards each other, it may be best to keep them separated to avoid potential harm.

Understanding the signs that cats do not like each other can help prevent conflicts and ensure a peaceful coexistence between feline companions.
